Sound.ALSA.Exception

ALSA does not distinguish between programming errors and runtime exceptions, which is sad, but we have to cope with it.

valueshowErrno :: Errno -> String

valueshow :: T -> String

valuerethrow :: IO a -> IO a

Converts any AlsaException.T into an IOError. This produces better a error message than letting an uncaught AlsaException.T propagate to the top.

valuestrerror :: Errno -> IO String

Returns the message for an error code.
